rS296570: Fix reporting of the CloudABI ABI in kdump.

Summary

Fix reporting of the CloudABI ABI in kdump.

Advertise the word size for CloudABI ABIs via the SV_LP64 flag. All of the other ABIs include either SV_ILP32 or SV_LP64.
Fix kdump to not assume a 32-bit ABI if the ABI flags field is non-zero but SV_LP64 isn't set. Instead, only assume a 32-bit ABI if SV_ILP32 is set and fallback to the unknown value of "00" if neither SV_LP64 or SV_ILP32 is set.

Test Plan

ktrace a CloudABI program and run kdump on the trace
